Answer: Seeds should be collected in the fall and stratified to break dormancy, then seedlings should be planted outdoors the following spring. Maple seeds need a warm, moist period, followed by a cold period. After harvesting, keep seeds at 68F to 86F in moistend potting soil, then refrigerate for 90-180 days. The seeds can then be planted outdoors (1/4 to 1 inch deep) in prepared soil. Good luck with your new trees!
